More information:

CVE-2020-8631

In cloud-init, relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function.

• CVE-2020-8632

  In cloud-init, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords.

For Debian 8 Jessie, these problems have been fixed in version 0.7.6~bzr976-2+deb8u1.

We recommend that you upgrade your cloud-init packages.
